Which of the following is true about the genetic code?

A. It is universal among all life on Earth.
B. It codes for chains of triglycerides.
C. It is unique to humans.
D. It is universal among animals.

It is universal among all life on Earth  is true about the genetic code.

A genetic code is a set of rules through which the information gets encoded in to the DNA or RNA sequences.The living cells then translates these information into proteins. The genes that acts as codes for proteins are made of tri-nucleotide.

These genetic codes are universal in nature for all the living organisms in the Earth. Only slight difference occurs. This is because one amino acid can be coded by more than one codon. A genetic code is considered to be repetitive in nature. Thus, It is universal among all the life on Earth will be true with the genetic code.

only about ten percent of the energy at one trophic level is passed on to organisms at the next trophic level. the remainder of the energy is used in life processes or lost as heat.
